Filed May 17, 1929 :Patented June 23, 1931 PATENT OFFICE PAULIBROCKHAUS, JR., OF OESTERAU IN WESTPI-IALIA, GERMANY VISE Applicationled May 17, 1929, Serial No. 363,827, and in lBelgium August 25, 1928.

lMypresent invention relates lto vises and has for its object to providea vise of a considerably simpler and cheaper construction than has beenpossible hitherto. This end I 'il attainfby the use of a base-platefurnished with two guide-rails, of which each is providedwith anapproximately U-shaped lateral channel with oppositely arranged guide*surfaces for the slip-faces of pendent guidecheeks of the vise-jaws. fThese guide-cheeks are on account of their novel attachment to.

the jaws to acertain degree resilient and thus adaptedk to automatically`accomplish their re'adjustment on Vthe worn guide-surfaces. But whenthe limit of this resilience has been reached the pendent guide-cheeksof the jaws are drawn inwards lfor a mechanical adjustment by means ofadjusting-screws lrotatably seated in said guide-cheeks and screwed intorectangular guide-blocks slidablyarranged in slots of said guide-rails.Simultaneously herewith these guide-blocks serve to limit the ioutwardmovement of the vise-jaws when they strike against the closed ends ofsaid slots.

My invention is applicable as well to vlses with a fixed and a movablejaw as to vises with two movable jaws, i. e. to the so-calledmachine-vises. arranged guide-rails a spindle provided with a right-handand a lettehand screw-thread is arranged to move said jaws alwayssimultaneously Y inv opposite directions, whereby said spindle passesthrough the pendent nuts of both jaws and is held against axialdisplacement by a xedarched abutment, which straddles said spindlebetween two collars of the latter.

A vise constructed in accordance with my present invention is shown byway of ex'- `ample in the accompanying drawings, in

which Figure 1 is a longitudinal section taken on `line 1--1 of Figure2.

Figure 2 is a plan-view of the improved vise. l Figure 3 is across-sectional view taken on line 3 3 of Figure 1, and

Figure 4 is a similar view taken on line 4-4 of the same figure.

exsl

Between the two vertically j The frame of the vise chiefly consists of abase-plate 1 whereon two guide-rails 2 are arranged parallel to eachother and integrally connected to said base-plate. These rails are alsoconnected with each other by cross-bars 3 and an intermediate verticalwall 4. Each rail 2 is on its outer face provided with an approximatelyU-shaped lateral -channel 2 with oppositely arranged guide-surfaces 5,which may bearranged parallel to each other G0 but preferably convergeinwardly, i. e. transversely of said channels, and are carefullymachined to serve as guide-ways for the visejaws 6, of which each isprovided with pendent guidecheelrs 7. These guide-cheeks solely c5 bearon said guide-surfaces 5 to leave gaps or air-spaces 8 between theunder-sides of the vise-jaws 6 and the webs and top-portions of therails 2, as clearly shown in Figures 3 and 4. The inclinedguide-surfaces 5 thus ob- 70 tained are designed to reduce the' frictionbetween them and the slip-faces ot the pendent guide-cheeks.Simultaneously herewith the pen dent guide-cheeks 7 are made resilientby the aid of the reduced web-like neclsl connected with the under-sideof the jaws, by means of which 'said pendent cheeks are enabled to takeup wear to a certain degree quite automatically. When, however, the wearhas reached a certainlimit the adjustment is regulated mechanically bymeans of adjusting-screws 9, which are rotatably seated in saidguide-cheeks 7 and screwed into internally threaded guide-blocks 10seated in slots 11 of the rails 2- and protected against S5 filings anddirt by shoulders 2 ofthe guiderails 2, as indicated in Figures 3 and 4.The adjustment thus obtainable can be conveniently executed on accountof the exposed position'of the headset the adjusting-screws 9 90 and maybe applied to either ot the guidecheeks of each jaw 6 alone or to bothjaws simultaneously.

The movement of the vise-jaws 6 to and from each other is accomplishedby means of a spindle '12 provided with a right-hand and a left-handscrew-thread, which engage the pendent nuts 13 of said jaws. These nutsare itted into said jaws and retained therein in their proper positionsby screws 14. The

V'spindle V12 is sustained at 4t in said inter- Y `mediate wall 4: andbesides this is straddled Y by an arched abutment 15 which entersbetween the collars 16 and 17 integrally connected with said spindle. Toprevent an axial displacement of the spindle said arched abutment isinserted into vertical slots 18 of the rails V2 and held inplacethereinby screws 19, as clearly shownin Figure 3.

Cover-plates 2O andQO are attachedto the jaws 6, of `whicliplates thecover-plates-ZU cooperate with a plate 21 secured to the Y Atop of thearched abutment 15 to form a cover of variable length, which at alltimes forms. an eiiective meansfor the exclusion of lilings anddirt'froni tliespindle-12- v The yimproved vise is of an exceptionallysmall kheight .and of a very simple construction and can on theseaccounts be'manufa'ctured at a lowercost'than thel known, inostf' lyrather complicated vises of: this class.
